Nanotechnology resolution affects many areas hf science including chemistry and chemical engineering since 1970, when enormous advances in the synthesis, characteri-zation and clarifying of high surface area materials have taken place. Development and commercial use of methods like sol-gel synthesis, chemical vapor deposition or laser induced sputtering allowed manufacturing of new advanced and highly efficient materials including porous adsorbents, at laboratory and commercial scale. In addition, characterization of these novel materials was being revolutionized by an availability of new analytical and high resolution microscopic instruments such as SAXS, HR TEM, STM, AFM and many others.

The main sources of air pollution in urban area are automobiles, burning of rubber, coal, wood and biomass in mall hearth. The variation in growth and different pigments in the leaves of two clones of Poplar tree species Populus deltoides L., G-48 and D-121 in Lucknow city, were found to be pollution load dependent and can be used as indicators of air pollution for early diagnosis of stress or as a marker for physiological damage to trees prior to the onset of visible injury symptoms (chlorosis and senescence). There was a decline in plant height and total chlorophyll content of leaves of P. deltoides, G-48 in commercial and industrial areas as compared to residential area. In case of P. deltoides, D-121 the plant height, shoot and root lengths increased but chlorophyll contents decreased, and carotenoids remained unchanged.

IPPTA Jl 2008, 20(1), 123-31.

A long term research project is being carried out in the Centre to address the bio-oxidation of the pulp mill wastewater in the aerobic treatment process with change of dominant and significant operating parameters and environmental conditions. The paper is based on the research findings on the effect of two operating conditions viz., pH and temperature on the operation of activated sludge process. The study has been carried out with the laboratory scale reactors operated under specified conditions with diluted pulp mill effluent having C_DE_OI,DD bleaching sequence. Aerobic biological process can be operated within the pH range of 5-9.5 without any compromise on COD and AOX reduction which are 65-71 and37.5-43%respectively;microbialconsortiais well structured and settles rapidly (SVI: 28 5 ml/g). The aerobic reactor can be operated even at pH of 9.5-11.5 with some compromise on AOX reduction (20-25%) and COD reduction (60 65%). Activated sludge process can comfortably be operated between 30-40°C without any difficulty in operation and compromise on reactor performance, and yield COD and AOX reduction of 68 and 37% respectively though there is some pin point floc formation; SVI of the sludge is 50 ml/g. The study indicates the importance of equalization and cooling of pulp mill influent before it is fed to the aerobic bioreactors for effective and higher pollutants removal.

Modern J Life Sci 2007, 6-7(1-2), 167-76.

Study was to assess the frequencies of aerofungal spores over the slum dumping areas in and around Daudnagar Nagarpanchayat with Special reference to reports on the counts of reported patho-allergic spores of various genera per m³ of the air and its subsequent effect on public health-hazards. An aerobiological survey of the aforesaid air was conducted with the use of rotorod air sampler fabricated and designed by Sinha et al. (1990) during the period Feb 2001-Jan 2003. Altogether 43 types of fungal spores were identified upto genus level. The most abundant reported allergenic fungal spores were found belonging to genera -Chaetomium (9,70%), Alternaria (6.0%), Penicillium (2.71%), Helminthosporium (2.43%), Nigrospora (1.92%), Curvularia (1.20%), Fusarium (0.97%) and Epicoccura (0.35%). A significant positive correlationships (P<0.05-0.09) was estimated between fungal spores concentrations and mean of maximum temperature, relative humidity and rain precipitations. Both qualitative and quantitative variations were observed to be affected by seasons and diurnal periodicity, during investigation period. The maximum concentrations of spores were recorded during August-September months in the both years of the research periods. The increase in spore concentrations was due to congenial condition of the areas. A survey of patients suffering from allergic diseases viz asthma, hayfever, rhinitis, dermatitis, conjunctivities and cough-cold out of 1000 selected persons of the areas was recorded. It was estimated that about 48% were found to suffer in rainy season foliowed by 30% in Winter and 22% in summer. About 15% patients were found to adopt anti-allergenic medicines regularly.

Arsenic contamination in groundwater of Bengal delta covering West Bengal and adjoining Bangladesh has become one of the worst environmental problems in the world. Arsenic in alluvial sediments is getting released into the groundwater, at places, crossing the permissible limit of drinking water standard and thus creating pollution. Gotra village in Chakdah block of West Bengal is one such arsenic-polluted area where majority of the tubewells are yielding high arsenic in groundwater. The village is situated over a curvilinear levee. The villages beyond this levee do not have much arsenic in groundwater. Groundwater in all 49 available tubewells of variable depths in Gotra village are analysed for elemental abundance. Four boreholes of 40m depth, two each from high and low arsenic-zones, are drilled for lithology and subsurface sediment analysis. Six additional boreholes, each of 30m depth are drilled for subsurface lithology. Porewater at two points from both high and low arsenic zones are collected through Waterloo profiler up to 40m depth. The geochemical interactions between sediment-porewater-groundwater are envisaged to propose the arsenic pollution mechanism. Sediment arsenic shows strong positive correlation with sediment iron, manganese and calcium. The porewater and groundwater arsenic show strong positive correlation with ammonia and alkalinity, weak positive correlation with iron, calcium and magnesium but weak inverse correlation with dissolve oxygen, manganese and sulfur. These relationships suggest that a reductive desorption process is acting as the principal mechanism for creating arsenic pollution in Gotra groundwater.

Nigeria has a total land area of 983,213 km² occupied by about 120 Million people: The interaction of these millions of people with their environment has left indelible mark on the landscape. Urbanization, deforestation, desertification, over population and all kinds of pollution are some of the resultant effects of man's interaction with his environment. These changes occur as the people attempt to acquire their seemingly endless desire for food, shelter, recreation and infrastructural facilities. Though these wants and desires contribute to the development of the country, the unwise use of the land and its resources produce negative impacts on the environment. Federal Environmental Protection Agency (FEPA) was established to control the Nigerian Environment, its resources exploitation and management. But field observation revealed that environmental degradation is growing at a rate worse than the pre FEPA period. Solution to these problems require going beyond the strategies and objectives of FEPA. Environmental protection techniques should be indigenized. It should be written and delivered in Nigerian languages. The design should take cognizance of the deferent ecological zone in the country and the people should be the agents. For an enduring legacy, Environmental Educational (which should include environmental protection techniques) should be included in primary and post primary school curricula.

Quantitative assessment of underground drinking water pollution of water of India Mark II (IM2) hand pumps at Moradabad for seven different sites, which are also deprived of other source of drinking water, has been carried out on the basis of calculated values of water quality indices (WQI). Water quality index for all the sites has been calculated with the help of estimated values of thirteen different physio-chemical parameters and drinking water standards prescribed by W.H.O. Underground drinking water was found to be severely polluted invariably at all the sites of study. People dependent on the water of source of study are prone to health hazards of polluted drinking water and water quality management is needed in the catchment area of study. Estimated higher values of different water quality parameters also verify the extent of drinking water pollution. Hence, assessment of water quality on the basis of calculated values of WQI is once again proved to be an effective tool.

Environmental characteristics such as topography, altitude, anthropogenic activity such as traffic, industrial gaseous effluents, proximity to all sources of pollution etc., have considerable influence on the abundance, residence time and retention of tropical trace gases over a locale. When the trace gas is toxic with its source at the surface of the Earth and has residence time of the order of several days, like in the case of carbon monoxide (CO), this trace gas becomes a criteria pollutant. Under the ISRO Geosphere Biosphere Programme (ISRO-GBP), a scientific study was initiated with a view to studying CO baseline at a tropical coastal station (Thiruvananthapuram) and to compare short-term CO measurements carried out in different environments such as a metropolis, a mining site and a pristine midland environment. CO is an air pollutant and is being monitored at a tropical coastal station Thiruvananthapuram since 2003 using an infrared analyzer:. Also, for short durations CO was measured at three other environmentally different sites viz., Palode (near Thiruvananthapuram, a midland hill station with dense vegetation at an altitude of 140m ASL on Western Ghats), New Delhi (metropolitan city) and at Jaduguda (a mining site in Jharkhand state) near Kolkatta. From these measurements, the behaviour of CO at different environments was studied. Ambient CO at these sites, their diurnal patterns and the effect of vehicular emission inferred from weekday-weekend behaviour was delineated. This study revealed that Palode has the lowest ambient CO, followed by Thiruvananthapuram, Jaduguda and then New Delhi. Modulation of ambient CO by the vehicular emissions was observed at New Delhi, Thiruvananthapuram and Palode, but was absent at Jaduguda. The results of the characteristic CO levels encountered at different environmental locations, the response to traffic, the main anthropogenic activity that affects CO levels, are presented in detail and discussed in the manuscript.

Treatment of wastewater at source has been identified as the best practice in environment management. High BOD (Biological Oxygen Demand) wastewater is a very common effluent in these days. Despite the fact that in some cases this wastewater is not directly toxic to the environment, It certainly results in depletion of oxygen in water body into which it discharged. Various alternatives are available for wastewater treatment. Most of them are energy incentive or require sophisticated maintenance. And due to lack of it most of the system fail, without providing a satisfactory result. Amongst all alternative resources of energy, solar energy is the most dependable resources. It is in abundance and environmental friendly. In the present case, we have suggested an oxidation pond system based upon solar energy and is best option for Indian conditions in medium size towns. We have designed a parallel scheme, so that during maintenance etc.at least partial treatment goes on. The final effluent is to be used for Fish culture or Irrigation etc.

In this analysis, results for main ions contributing towards TDS and NO-₃ are being reported. On comparing the results against drinking water quality standards laid by Indian Council of Medical Research (I.C.M.R.M), it is found that most of the water samples are non-potable for human beings due to high concentration of one parameter or the other. Most of the samples have total dissolved solids values much higher than maximum permissible levels by I.C.M.R., which is 1500 ppm. The high value of these parameters may have health implications and therefore, needs attention.}

The chemical analysis data of ground water samples reveals that the ground water pollution is increasing in all wells situated along both the banks of Jojri River. It has been observed that the wells having depth of water more than 15m below the ground level are not much affected by the industrial effluents. It may be due to the fact that effkient water is not penetrating (leaching) beyond this depth. It may be concluded that wells located within 200 m area are not suitable for either irrigation or for drinking purpose.

Ind Res Commun 2008, 2(1), 26-32.

Pollution in our environment is increasing in concentration & therefore having become a preventive conservation priority. An attempt has been made to study the pollution level of the Khan River. The quality of the water of Khian River has been studied at the different places where the domestic & industrial waste is being mixed with the water. The presence of the synthetic chelating agent ethylene di amine tetra acetic acid in Khan River has a significant impact on the efficacy of wastewater treatment. Results of laboratory experiments designed to simulate indicate that a portion of pollutant metal-EDTA species can be converted into Fe EDTA by addition of FeCl₃ during simulated treatment. Addition of FeCI₃ also resulted in improved metal removal by adsorption. The combination of these two processes improved removal of Cu and Zn by 20% during stimulated treatment. Complex (Fe EDTA) is quickly degraded by direct photolysis, whereas other EDTA species are very slowly transformed. The formation of Fe EDTA during treatment plays a potentially important role in metal removal and should be considered in future evaluations of wastewater treatment plant performance.

The metal bioccumulation capability and effectiveness of eight aquatic macrophytes Eicchornia crassipes (water hyacinth), Pistia stratiotes (water lettuce), Lcmnci major (duckweed), Ipomoea aquatica (kang kong), H.verticillata, Nymphaeae spp. (water lilies), Nelumbo nucifera (lotus), Nymphoides indica were investigated for the removal of three heavy metals Fe(II), Cd(II) and Cu (II). These plants were grown at 2.0 mg/L concentrations of metals in laboratory experiment. Within a span of 6 days, the plants were capable of removing about 65- 95% of the selected heavy metals. The sorption process was very rapid for copper removal. Highest removal was observed on 6 day of experiment in all macrophytes. It was observed that macrophyte Nymphoides indica as the most efficient for the removal of selected heavy metals followed by Nelumbo nucifera (lotus), and Nymphaeae spp. (water lilies). The trend of the sorption is Fe (II) > Cd (11) > Cu (II). Results from analysis confirmed the accumulation of different metals within the plant and a corresponding decrease of metals in the water. Plants have accumulated heavy metals in its body without the production of any toxicity or reduction in growth. Selected plants shown a wide range of tolerance to all of the selected metals and therefore can be used for large scale removal of heavy metals from waste water

Air pollution and associated health problems have assumed alarming proportions in India. This article describes the clean environment initiatives taken by the higher judiciary over the past 3 decades. These efforts, especially in the aftermath of the Bhopal tragedy have aided the development of Indian Environmental Law. Judiciary has indeed been an early maestro of environmental protection through "judicial activism", mainly through Public Interest Litigations. The article discusses this issue against the backdrop of our Constitution, including the Directive Principle of State Policy and Article 51 A(g), 47, 21; "Sustainable Development and intergenerational equity", "Precautionary principle" and "Polluter pays principle", relocation of hazardous industries, development of green belts and open spaces, control of vehicular pollution and occupational exposure. These judgements uphold the spirit of right to pollution free air in India.

Study was carried out to observe the phytotoxic stress of distillery effluent on the seed germination of Oryza sativa L. The study revealed that 25 % concentration of effluent promoted seed germination and seedling growth of two cultivars of Oryza sativa cv. Pusa-44 and Saka-4. The higher concentration of effluents retarded not only seed germination but also seedling growth. Emergence index, vigour index, germination relative index, phytomass and chlorophyll content were found significantly higher in 25 % concentration than 50 % and 100 % of distillery effluent over control. It is recommended that 25 % distillery effluent may be recycled as ferti-irrigation for sustainable agriculture in Indian scenario for environmental conservation.

During the process of storage large excess of ash pond effluent, after settling of fly ash finds its way into the nearby water bodies. This ash pond effluent, being repository of essential plant nutrients containing fine suspended particles of ash has a potential for being suitably used for irrigation of different crops. Taking a clue from this, laboratory experiment was designed to study the effect of different concentrations of fly ash effluent on germination, morphology and biochemical contents of maize seeds. The results showed that the effluent had a telling effect on the growth of maize seeds in respect of aforesaid parameters. Chlorophyll-a, chlorophyll-b and also the carbohydrate content in leaves of maize were found to have increased significantly due to the fly ash effluents in different concentrations i.e. RW : FAE (40:60 ratio vol/vol). This indicated that the concentrations enhanced seed germination rapidly. The root and shoot length too increased at the said concentration. The results also suggest that the percentage of germination and growth parameters have a good correlation with chlorophyll and carbohydrate contents due to nutrients in fly ash effluents and some other plant growth promoting agents that might also be present in the effluents.

Ultra Scient phys Sci 2008, 20(2), 373-8.

Fluoride concentration has been quantitatively determined for ground water samples from Varattupallam and Kumbaravani Pallam watershed of Bhavani Sub-Basin. The results do not indicate large variation. A minimum of 0.2 mg/l to maximum of 2.0 mg/l in the post monsoon and a minimum of 0.2 mg/l to a maximum of 11.00 mg/l in pre monsoon samples have been observed in the study area. Most of the samples show < 1.5 mg/l except in few locations. The sample near K..T. Ammankoil Pudur (Loc. No. 25) and Kattupalayam (Loc.No.46) have recorded slightly higher concentration >1.5 mg/l during the post monsoon, where as during pre monsoon, the sample near Palliapalam recorded anomalous high concentration of fluoride (11.00 mg/l). The studies of fluoride concentration do not indicate any significance alarming impact except the area near Palliapalayam. The possible source can be attributed to the influence of fluoride bearing minerals in the country rock Fissile Hornblende Biotite Gneiss.

Performance and phyto-remediation capacity of three aromatic grasses viz., palmarosa (Cymbopogon martinii), lemon grass (Cymbopogon flexuosus) and vetiver (Vetiveria zizaniodes) were evaluated during 2003-04 in lysimeters filled-in with a sandy loam soil. Variable levels of cadmium (Cd) were created through the application of CdCl₂ at the rate of 0 (control), 5, 10, 20, 50, 100, 150 and 200 mg Cd kg^-1 soil. Growth, biomass productivity and the oil yields of all the grasses decreased with increased Cd levels. The relative tolerance followed the order: Vetiver > palmarosa > lemon grass. Significant reductions in the biomass of palmarosa and lemon grass were monitored at > 20 mg Cd kg^-1 soil, whereas the productivity of vetiver could be sustained up to < 50 mg Cd kg^-1. The Cd content of foliage increased with its concentration in soil but most of it was retained in the roots itself e.g. root Cd contents were 33 times the shoot Cd content in vetiver. Amongst the three grasses, Cd content in foliage of palmarosa was three times its content in shoots of lemon grass and vetiver. Considering the overall higher tolerance and removal of Cd by vetiver, it seems to be the most suitable candidate for detoxification of the Cd-contaminated soils and avoiding the entry of heavy metals in food chain.

Jatropha (Jatropha curcas L.) seed coat was investigated for removal of Cu (II) from aqueous solutions. Impact of pH of the solution, sorption time, and initial metal ion concentration on sorption capacity was investigated. Adsorption equilibrium was reached in 80 min and 82-89% of Cu (II) was removed by Jatropha seed coat at initial Cu (II) concentrations (20-50 mg l^-1). Adsorption data, analyzed using Langmuir, Freundlich and Redlich-Peterson isotherms, showed that adsorption equilibrium followed Langmuir and Freundlich isotherms. Kinetics of adsorption followed Elovichian rate equation at 30°C. The most plausible mechanism of adsorption seemed to be electrostatic attraction of Cu (II) towards lignocellulosic polar groups of Jatropha seed coat. The study showed that powdered Jatropha seed coat can be used as an adsorbent for removal of Cu (II) from wastewater.

The demand for water has increased manifold due to population explosion and consequent increase in irrigation and industrial development. As the surface water resources are limited and mainly depend on monsoon, the increased water demand is being sustained by ground water source through many new tube wells tapping deeper aquifers. Vanur block is underlain by Coastal Alluvium, Cuddalore Sandstone, Vanur Sandstone, Limestone and Charnockite. The Vanur Sandstone is one of the main aquifers in the area and is the source for irrigation as well as for drinking water supply to Tindivanam town. The increased extraction of ground water has resulted in a steep decline of ground water levels. An attempt has been made in this paper to study the long term behavior of ground water levels in this aquifer using the historical water level data collected from the observation wells being monitored by Auroville water service (Harvest) and Central Ground Water Board. The analysis of water level data indicates a long-term decline in the major part of the area. The result of the study indicates that urgent steps including strict regulatory meseaures on ground water extraction and augmentation of ground water resources through suitable artificial recharge structures may have to be initiated in the area to ensure sustainability of ground water extraction structures and to prevent possible saline water ingress.
